Implant for tissue lifting

Abstract

Provided is an implant for a tissue lifting that is inserted between sagged or wrinkled skin and subcutaneous muscle to enable pulling and smoothing tissue, wherein the implant for tissue lifting can be inserted between skin and subcutaneous muscle, includes the bioimplantable thread having a distal portion where pulling is required and a proximal portion where the bioimplantable thread is pulled, and the mesh member that is fixedly coupled to the distal portion of the bioimplantable thread and has numerous pores wherein bodily tissues grow and fill the pores.

The invention claimed is: 
     
       1. An implant for tissue lifting comprising:
 a bioimplantable thread configured to be inserted between skin and subcutaneous muscle and having a distal portion where pulling is required and a proximal portion that pulls on the distal portion; and 
 a mesh member having a plurality of pores, the mesh member having an outer perimeter, 
 wherein cogs are formed on the bioimplantable thread and the cogs protrude from a surface of the bioimplantable thread, 
 wherein the cogs on the bioimplantable thread are arranged to allow passage of the bioimplantable thread in a first direction through tissue and resist movement of the bioimplantable thread in a second direction and are configured to penetrate and pull tissue to facilitate tissue lifting, 
 wherein both ends of the mesh member are fixed to the surface of the bioimplantable thread such that the bioimplantable thread is configured to be linearly disposed within or adjacent to the mesh member, 
 wherein the mesh member has a first end portion, a central portion connected to the first end portion, and a second end portion connected to the central portion and disposed on an opposite side of the first end portion, 
 wherein the first end portion and the second end portion are tapered in a longitudinal direction of the mesh member and gradually thinning toward the respective both ends thereof, 
 wherein the central portion includes a plurality of oval-shaped elements arranged in a single row, each oval-shaped element extends from a first side of the outer perimeter to a second side of the outer perimeter opposite the first side, the plurality of pores are formed in the plurality of oval shaped elements, and the plurality of oval-shaped elements are attached to each other to be consecutively arranged along the bioimplantable thread. 
 
     
     
       2. The implant for tissue lifting of  claim 1 , wherein the bioimplantable thread and the mesh member are coupled with each other using a process selected from the group consisting of: heat bonding, knotting, using a medical adhesive material, and combinations thereof. 
     
     
       3. The implant for tissue lifting of  claim 1 , wherein the bioimplantable thread has a thickness of about 0.25 mm to about 1.5 mm, which is a thickness that secures safety of a surgery while not showing external marks of the surgery. 
     
     
       4. The implant for tissue lifting of  claim 1 , wherein the bioimplantable thread comprises a cogged portion where the cogs protrude from the surface of the bioimplantable thread, and a cogless portion separated from the mesh member that integrally connects to the cogged portion and omits the cogs to be fixed on fascia. 
     
     
       5. The implant for tissue lifting of  claim 4 , wherein the cogged portion comprises a removing portion that is configured to penetrate the skin and that is configured to be pulled after the removing portion penetrates the skin, wherein the removing portion has a length within a range of about 15 mm to about 25 mm. 
     
     
       6. The implant for tissue lifting of  claim 5 , wherein the mesh member is coupled at about 15 mm to about 25 mm behind a frontal portion of the removing portion to adjust a pulling of the mesh member. 
     
     
       7. The implant for tissue lifting of  claim 4 , wherein the cogged portion has a size of a space between adjacent cogs in a range of about 2 mm to about 4 mm, and when the cogs are incisive cogs, a depth of incision is 25% or less of a diameter of the bioimplantable thread. 
     
     
       8. The implant for tissue lifting of  claim 4 , wherein the cogs of the cogged portion are arranged in a spiral form on the surface of the bioimplantable thread to distribute support strength. 
     
     
       9. The implant for tissue lifting of  claim 1 , wherein the mesh member is formed by knitting or injection molding. 
     
     
       10. The implant for tissue lifting of  claim 9 , wherein the mesh member is heat treated to maintain tensile strength. 
     
     
       11. The implant for tissue lifting of  claim 1 , wherein the implant for tissue lifting comprises a bioabsorbable medical polymer material selected from polydioxanone, poly-(l-lactic) acid, polyglycolic acid, polycaprolactone and a copolymer thereof that are harmless to a human body and are absorbed in vivo over time, or a biocompatible medical polymer material comprising polypropylene and a mixture thereof. 
     
     
       12. The implant for tissue lifting of  claim 1 , wherein the bioimplantable thread of the implant for the tissue lifting has a length of about 120 mm to about 230 mm to expose a portion the bioimplantable thread, and a guiding portion separated from the mesh member that extends without the cogs on a surface of the bioimplantable thread for guiding a penetration of the bioimplantable thread being inserted into an inserting cannula. 
     
     
       13. The implant for tissue lifting of  claim 1 , wherein the cogs are also located on portions of the bioimplantable thread that extend from both ends of the mesh member. 
     
     
       14. The implant for tissue lifting of  claim 1 , wherein the cogs are arranged in a spiral form on the surface of the bioimplantable thread.
